In this paper, we present a framework called CoUniverse, designed for building real-time user-empowered collaborative environments to work primarily on high-speed networks with true high-bandwidth applications such as uncompressed high-definition video. The system is designed for unreliable experimental infrastructures and therefore its operation relies(More)
We describe an architecture for distributed collaborative visualization that integrates video conferencing, distributed data management and grid technologies as well as tangible interaction devices for visualization. High-speed, low-latency optical networks support high-quality collaborative interaction and remote visualization of large data.
We describe a high-quality collaborative environment that uses High-Definition (HD) video to achieve near realistic perception of a remote site. The capture part, consisting of a HD camera, Centaurus HD-SDI capture card, and UltraGrid software, produces a 1.5 Gbps UDP data stream of uncompressed HD video that is transferred over a 10GE network interface to(More)
—This article describes a distributed classroom experiment carried out by five universities in the US and Europe at the beginning of 2007. This experiment was motivated by the emergence of new digital media technology supporting uncompressed high-definition video capture, transport and display as well as the networking services required for its deployment(More)
Providing secure, extensible, pervasive and easy to implement collaborative environment for medical applications poses significant challenge for state-of-the-art computer systems and networks. In this paper, we describe such a collaborative environment developed for Ithanet project, based on Grid authentication mechanisms. Significant effort has been put(More)
The workshop will provide an insight in solving real-world problems using the high-quality, low-latency media transmissions over (high-speed) networks and implemented by the UltraGrid and CoUniverse software developed by CESNET. During the workshop we'll go step-by-step through a deployment of UltraGrid and CoUniverse for a multi-point media transmissions(More)
Primary cortical areas for motor, sensory and sensitive functions are localized in certain areas of the brain cortex. In clinical practice, cross sectional imaging (computer tomography and magnetic resonance) is wildy used for diagnostics purpose, treatment planning and follow up of the patients. Accurate orientation in brain structures is necessary for the(More)
